I really dig Dyson's thieving skills, but I am thinking of something even easier.
All thieving could be a ability check, specifically a dexterity ability check. Obviously all characters have dexterity scores, so I need to figure out a way to make thieves slightly better at all things thieving.
Roll under dex and add the following modifier to the roll based on level. Obviously a roll of one is great success! and a twenty is a total epic failure.
Thievery covers the following old schoolisms: open locks, find & remove traps, pick pockets, move silently, climb walls, hide in shadows, hear noise
EDIT: +Zak Sabbath suggested that this idea could be scaled with the thief's backstab ability, which is a good idea!
